V m Fig. 2 is a fragmentary View infplan, showing the frame suspension; Referring more particularly to tl'lQClIfiW- ings, 10 indicates a Vehicle main frame 'Which is disposed above an axle 11 of a suit able runmng gear. The axle is provided with Wheels, as indicated by dottedlines in Fig. -1' and is free to float, as limited by r radius rods 12. These rods are'pivotally disposed around the bodyof the axle attheir on'elends and are .pivotally connected to the main frame" bra-1:5 13 at; their opposite v ends; The bolts 13 are mounted ithin ,7 bracketslsecured to 'the under-face of the frame side rails;- Radiusrods are? here shownasfermed in two parts which tele and may beadjusted as regard their length,

by means of lock members 15;. 'The bel'ts13 a carry 'spring 'shackles l6. These shackles are spacedin" relation to; eachiother j iand'f'stand, upon the opposite sides of'semi- "elliptical S ringer? 1 The forward ends oft-he springs 17 terminate a't'points abovethe bolts- 13 and 'aregthere engaged by'sprin'g bolts-18 also which passjthrou'gh the eyes of the springscured inp-ivotal relation thereto by the shackle bolts {1-8.1} The body" jortion 22 of the basal: extends lcngitudinal y of springs 17 and 'isin central alignment therewith; Its

rear portion is formed with an enlargedeyefl 24 through whichtherea'r end of'the springs s 17 extend; lever vextension 25 forms the: terminating-end of the bar 21 and is held by" -a b'olt 26 to the movable member 2-7 of a 7 Y pneumatic cushion spring 28.

equalizer bar 21 5 I In operation," the vehi'cle'isassenibled and the springs 17 securedlupon the axle by means of spring seats 32. lThe equalizer' bars and pneumatic cushions are then dis-' posed. in the assembled relation shown in F ig. l and the vehicle is in condition foruse: As the ehicle passes along the road-f ay, any relative movement of theaxle 11 r in relation to the main frameIO will cause i deflection of the springs 17. When the axle moves upwardly it, will follow an arcuate path on account of the radius rods 12. The

springs 17 will thereupon be deflected in the usual Way. This relative movementhas between the inetal's1' rings and the main frame will be transmitted to the air springs through the shackles 19 and equalizer bar a '24. fThe shackle 16 will permit whatever longitudinal; movement may be required on the part of the equalizer bar inorder to preventbinding. I 1 Itwill thus be seen that the frame sus lQ 'pensionJ here provided will allow a. resilient ,suppelftlofa main frame upon a vehicle running gearand atthe saine'time will provide a pneumatic cushion for absorbing excessive tins and I overcoming objectionable rebojund w vhich would be produced by the l I resilient support under ordinary conditions. ff iavingthus described my invention, what Ii'clainianddesire tosecure by-Letters' Pat fent'isz.
